That's not what i said at all. I said some things have been really great, some really not so great. This isn't even a controversial view among long-time llvmers.

Heck, last time i asked him (a few months ago), even Chris Lattner agreed with my view, and he used to run his stuff at Apple, so i don't think it's unreasonable.

I think it's perfectly okay to be cautiously optimistic instead of fawningly happy.

Do you actually have data or a real argument you'd like to use to suggest otherwise (IE that it's been all overwhelmingly positive?)
